Passing multiple Lists in single parameter

Question

Hi Team

I have below requirement.

There are 3 list with different class type.

Example:

List<Customer> lst1=new LIst<Customer>();
List<CustomerOrder> lst2=new List<CustomerOredr>();
List<CustomerTransaction> lst=new List<CustomerTransaction>();

i want to add three list into one list like ,List<List<T>> lstMul=New List<List<T>>();

lstMul.add(lst1);
lstMul.add(lst2);
lstMul.add(lst3);

Above lstMul will be send to the entity framework BulkInsertOrUpdate method

context.AddUpdateEntityData(lstMul)

---

ENtityframework method

    **public int AddUpdateEntityData(List<Dynamic> lstDynamic)**
    {

    _context.BulkInsertOrUpdate(lstDynamic.Item1);  ----Inserting Customer  List        
    _context.BulkInsertOrUpdate(lstDynamic.Item2);----inserting CustomerOrder List
    _context.BulkInsertOrUpdate(lstDynamic.Item3);-----inserting CustomerTransaction List
    _context.savechanges();

     return 1;

    }

Please suggest how we can achieve above reqirement.

You can put all the Lists in a class, a container class/object and pass the container class/object as a parameter.

A List<T> is a strong typed collection meaning if it's List<Book>, then only Book objects can be loaded into the List<Book>. You can't load a Car object into a List<Book>, becuase an exception will be thrown.
